The Cabinetry / Our Commitment

Handcrafted

Beneath the surface of Helix’s elegant exterior lies rigid MDF
construction. Interlocking joinery maximizes the strength of the
cabinet parts. Polyester fiberfill is selected for internal damping.
A sharp rap on the enclosure will leave you with little more than
bruised knuckles. Each cabinet is impeccably finished on all ex­posed surfaces with select veneers. The exquisite finish is hand­rubbed several times to assure a patina at home with the most
elegant decor.

Our Commitment

A great deal of forethought, love and satisfaction is instilled in
each piece of Legacy workmanship. We take pride in getting to
know many of our customers on a first name basis. The re­nowned “Legacy Satisfaction Guarantee” backs your purchase of
this product.

Unpacking Your Speakers

Helix is a large loudspeaker requiring assistance of a dolley, a cord­less Philips screw driver and two or more physically capable individu­als to uncrate and locate.

Here are some uncrating tips:

1. Carefully remove screws securing the lid of the crate, and lift
panel away. Locate subwoofer power cord and set aside.

2. Next remove front panel of crate and set aside.

3. Remove side panel of crate as shown.

4. Remove foam from top lid and use as ramp as shown in bot-

tom photo.

5. Helix is setting on four heavy duty casters, allowing is to be

maneuvered on level ground.

6. Take care to avoid damaging floors when locating.

7. Helix is a field serviceable loudspeaker, so it is unlikely that an

entire cabinet would ever need to be returned to the factory.
However, when moving or storing, the crates are extremely
useful for protecting the cabinets.

Speaker Placement

1. A speaker setup (left) that works well with HELIX follows
these ratios:

Distance, d1, between the speakers (center to center) =
Distance, d2, from plane of speaker front to listener.

2. Toe the speakers into the listening area. In most circum
stances crossing speaker axes just slightly behind of the lis
tener’s head works best. This will broaden your sweet spot
horizontally. If dispersing into an L-shaped seating arrange
ment you might find the best results by aiming the left
speaker at the right most seating position, and the right
speaker at the left most seating position.

Speaker Placement

Room reflections and resonance typically contribute 85% of the
total energy arriving at the listener’s ears. Often, a loudspeaker
designed to measure well under laboratory conditions, will be­come blurred, dissonant and placement dependent in the actual
listening room.

The HELIX speaker has a carefully shaped polar pattern. This as­sures that the wave-launch generated will sum coherently at the
listening position. To the left is an illustration of how our new He­lix speaker performs.

Conventional speakers (top) beam treble and scatter midrange
about the imaging room, while loading up the corners with boom­ing, lingering bass.

Legacy’s directivity controlled designs focus the radiation pattern
toward the listeners (bottom). The result is a broader sweet spot
for imaging, markedly greater clarity and a slamming bass line
that is quick and tight
